732169 divided by 75 
The aim is to understand the frequency of 75 in 732169.

On to step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 75

Let's proceed to step 2:
The number 75 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 75

On to step 3:
75 goes into 732 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 9.0
If we take 675 away from 732, we end up with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 75

Going ahead to step 4:
571 divided by 75 is 7 with a remainder of 46.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 525 from 571 leaves us with 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 75

Advancing to step 5:
75 can be fit into 466 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 976.0
Subtracting 450 from 466 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 75

Advancing to step 6:
When dividing 169 by 75, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 9762.0
Subtracting 150 from 169 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
75 can be fit into 190 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 9762.2
The remainder is 40 after subtracting 150 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
75 goes into 400 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9762.25
Subtract 375 from 400 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9762.253
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 75 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9762.2533
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 9762.2533, with a leftover of 0.00025.
